Map History: You are an explorer who made a trip to Greece. In one of your expeditions, you find a sort of ancient Greek temple for worshiping the moon goddess, Selene. You marvel at it, but everything starts to get unclean when night comes. It was a form of defense against enemies. When night arrives a platform detects lunar light and releases water.

I feel like there is an over-usage of the colour blue. You should use more harmonious colours (colours which are close to blue) to represent this or you can even use a colour opposite to blue or use more darker colours to make the blue pop out even more.
I’d rather you make the pillars and place white but make some blue cracks seep through the walls around the beginning areas. Probably doing this on a button function to make the map even cooler!
